WASHING-MACHINE.

T 0 all wiz-0m it may concern:

Be it known that I, ROLAND A. McDoNALD, a citizen of the United States,residing at St. Joseph, in the county of Buchanan and State of Missouri,have invented certain new and useful Improvements in Washing-Machines,of which the following is a specification, reference being had thereinto the accompanying drawings.

This invention relates to a machine which combines within itself awashing machine and extractor or Wringer and a rotary drying tumbler ordrier, and more particularly, to a motor driven or manually driven drumor cylinder that is adapted to contain the clothes, which cylinderrevolves within the primary cylinder, the primary cylinder beingsupported upon a suitable frame or support.

Another object of the invention is the construction of an eficient andsimple auxiliary or rotatable cylinder that lis provided with doors heldclosed by springs, and which cylinder is divided by a partition,producing compartments in the cylinder.

Another object of the invention is the construction of a washing machinethat can be heated for heating ythe water in the machine or the heatingmeans utilized, when desired, for drying the clothes in the machine,while they are being tumbled about by the motion of the machine.

IVith these and otherobjects in view, my invention comprises certainnovel combinations, constructions and arrangements of parts as will behereinafter described, illustrated in the accompanying drawings, andmore particularly pointed out Ain the appended claims.

In the drawings:

Figure 1 is an end view, in elevation, of a machine constructed inaccordance with the present invention, -while Fig. 2 is a side view ofthe same.

Fig. 3 is a sectional view, taken von line 3-3, Fig. 4, and looking inthe direction of the arrows.

Fig. 4 is a sectional view, taken on line 4 4, Fig. 3, and looking inthe direction of the arrows.

Fig. 5 is an enlarged perspective view of the auxiliary cylinder.

Fig. 6 is an enlarged fragmentary sectional view of the auxiliarycylinder.

Fig. 7 is a sectional view, taken on line 7-7, Fig. 5.

-Speccation of Letters Patent. Patented Dec,

Application led May 29, 1920. Serial No. 385,164.

I Referring to the drawings by numerals, 1 designates a suitableplatform,t0 which is secured the frame 2 of the machine; the

frame 2 is preferably made of metal, and

upon its upper end is supported the primary cylinder 3; the cylinder 3has an opening 4, closed by the hinged door 5.

Heatingmeans, such as a gas jet 6, is placed under the primary cylinder3, whereby said cylinder may be heated for heating water containedtherein, or when water has been emptied from the cylinder, by means offaucet 7', the heat generated from thejet 6 may be utilized to dry theclothesthat may -le contained in the revoluble auxiliary cylin- Theauxiliary cylinder is preferably perforated (Figs. 3 and 4) and in thecylinder is a perforated partition 8, dividing the cylinder into twocompartments. Extending through the cylinder 7 and partition 8 is ashaft 9; this shaft is journaled upon ball-bearings 10, and to one endof the shaft, outside of the primary cylinder 3, is suitably -attached acrank handle 11, and to the other efliciently in place upon theauxiliary cylinder. A pair of inwardly-swinging doors 17 are hinged at18 upon the auxiliary cylinder,

and the resilient or springy bands extendv through integral eyelets 19,projecting from the outer face of the doors,thereby permitting vthedoors to be pressed inwardly to c allow the insertion or the removal ofclothes from the compartments of the auxiliary cylinder, but upon theoperator removing pressure from 'the doors 17, they will immediatelybeclosed by the action of the bands or wires 16, and any suitable latchdevice or catch may be used, at 20, for holding the doors 17 normally intheir closed position.

I found from experience that the dividing -of the auxiliary cylinderinto sections or compartments produces a better balance of the load asthe machine washes, wrings and dries and enables the cylinder 7vto berotated in one direction without tangling the clothes; I lclaim this tobe a new principle in this type of a one-way washing machine.

My machine is what may be called a three-in-one machine; that is, it isa washer, extractor or wringer and drier. It does the work of a wringerand wrings by centrifugal'force without the assistancev of heat or anyother agency. It is a drier when the heat is applied to the machineafter they process of wringing or extracting has been completed.

In operating my machine, it will be necessary to run the same at onespeed for washing clothes, and at another for extracting, and yet atanother for drying.

It will be appreciated that my machine may be adapted for use in alaundry or for use in a dwelling or home. Further, while I havedescribed the preferred embodiment of my invention, and have illustratedthe same in the accompanying drawings, certain minor changes oralterations may appear to one skilled in the art to which this inventionrelates, during the extensive manufacture of the same and I, therefore,reserve the right to make such alterations or changes as shall fairlyfall within the scope of the appended claims.

What I claim is:

1. In a washing machine, the combination with a frame, a primarycylindercarried by saidl frame, of an auxiliary cylinder mounted withinsaid primary cylinder, a partition in said auxiliary cylinder, a hingeddoor carried by said auxiliary cylinder, and springs means extendingthrough a part of lsaid partition and'through a part of said door fornormally holding the door in a closed position upon the auxiliarycylinder. 2. In a washing machine, the combination with a frame, aprimary cylinder upon said frame, of an auxiliary cylinder in saidprimary cylinder, a partition in said auxiliary cylinder and havingportions of its ends extending through the auxiliary cylinder, in-

wardly-swinging doors on the auxiliary cylinder at opposite sides of thepartition, and resilient bands positioned in the ex-tended ends of thepartition and fastened to the doors for moving the same to a closedposition after they have been swung inwardly tured lugs of the partitionand Vthrough the eyelets of the doors ,for causing the doors to swingoutwardly to a closed position after said doors are pressed inwardly forthe placing of or removing of clothes from within the auxiliarycylinder'.

In testimony whereof I hereunto afiix my signature.

ROLAND A. MCDONALD.
